Southampton's population increased by about 19,400 between the last two censuses. This semi-automated article highlights some of the most notable changes among the local population.
The population reached nearly 240,000
In the decade to 2011, the population of Southampton increased by 8.9%, from about 217,000 to 237,000.
The addition of about 19,000 people means this area's population increased faster than the rate of growth across England (up 7.9% since the 2001 census).
In 2011, Southampton was home to, on average, 34 people per football pitch-sized piece of land. This made it the South East's second-most densely-populated unitary authority.

A younger Southampton
Census 2011 data also show a change in the local population's average age.
Between the last two censuses, the median age of Southampton decreased by one year, from 33 to 32 years.
This area had the third-lowest average age in the South East and remained younger than the average local authority area across England (39 years of age).
The fall in age was because of an increase of just under 6,300 people between the ages of 20 and 29 years, while the population between 70 and 79 years decreased by just over 900.
About 22.0% of people in Southampton are aged between 20 and 29 years

Religion in Southampton
Of those who chose to disclose their religious affiliation in Southampton, the largest percentage point increase was among those who said they had no religion, rising 12.6 points between 2001 and 2011. The census question about religion is voluntary, so varying response rates mean caution is needed when comparing figures between different areas or between censuses.
In 2011, 36.1% of respondents in Southampton said they had no religion, up from 23.5% in 2001.
Across the South East, the percentage of respondents who described themselves as having no religion increased from 17.9% to 30.1%, while across England the percentage went from 15.7% to 26.5%.
Around 55.4% of respondents in Southampton said they were Christian, down from 71.3% in 2001. About 4.5% said they were Muslim, up from 2.1% a decade prior.
There are many factors that can cause changes to the religious profile of an area, such as differing patterns of ageing or relocating for work or education. Changes may also be caused by differences in the way individuals choose to self-identify between censuses.
